The ones listed at the beginning of the thread. The Zella High Waist Live-In Leggings. I bought the long length but the crop may also have issues. I would call the 800# if you have any doubts- they can look up the order and tell you if the style you bought is recalled.
What is unusual in this case is that this is a recall for possible health concerns with a Nordstrom product. I hope others will return theirs as well.
I brought the long ones and they seem fine...
